Download the ZD421 Setup Utility
There is no file hosted on this page. The links below go directly to Zebra Technologies' own support site — the only trustworthy source for ZD421 drivers and setup software.
Why we don't host the installer here. Printer "driver download" sites that host their own copies of setup files are a common way malware gets distributed. The safe approach is always to download directly from the printer manufacturer's own domain. That's what the buttons below do.
